Theorem REF  shows how the general-form method for calculating the CGFD with a projection matrix is equivalent to the GFD constructed after reparameterizing (REF ) to an unconstrained space. Theorem REF  also shows that using the Lebesgue-Riemannian measure is equivalent to the method given by [1]}, who uses the Hausdorff measure to find the area measure of an embedded subspace. This equivalency is outlined as a theorem in [2]}.
